This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port. Before this change ifconfig diplayed potentially stale information for ports that were administratively down. - Always recalculate and reapply L1 config on a transceiver change. - Display PAUSE settings in ifconfig. The driver sysctls for this continue to work as well. r321103: cxgbe(4): New ioctls to flash bootrom and boot config to the card. r321179: cxgbe/t4_tom: Log more details about the newly ESTABLISHED tid to the trace buffer. r321390: cxgbe(4): Install the firmware bundled with the driver to the card if it doesn't seem to have one. This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters. These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision. These timers are already displayed in microseconds in the sysctl MIB. Add variables to track these tunables while here. r322123: cxgbe(4): Avoid a NULL dereference that would occur during module unload if there were problems earlier during attach. r322167: cxgbe(4): Add the T6 and T5 Unified Wire configuration files to the kernel, just like for T4, when the driver is compiled into the kernel. r322425: cxgbe(4): Save the last reported link parameters and compare them with the current state to determine whether to generate a link-state change notification. This fixes a bug introduced in r321063 that caused the driver to sometimes skip these notifications. r322549: cxgbe/t4_tom: Use correct name for the ISS-valid bit in options2. r322914: cxgbe(4): Dump the mailbox contents in the same format as CH_DUMP_MBOX. r322960: cxgbe(4): Verify that the driver accesses the firmware mailbox in a thread-safe manner. r322962: cxgbe(4): Remove write only variable from t4_port_init. r322964: cxgbe(4): vi_mac_funcs should include the base Ethernet function. It is already used in the driver as if it does. r322985: cxgbe(4): Maintain one ifmedia per physical port instead of one per Virtual Interface (VI). All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults. The congestion channel map, which is still fixed, needs to be tracked separately now. Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering. Disable it by default when running on Intel CPUs. r328420: cxgbe(4): Do not display harmless warning in non-debug builds. r328423: cxgbe(4): Accept old names of a couple of tunables.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port. Before this change ifconfig diplayed potentially stale information for ports that were administratively down. - Always recalculate and reapply L1 config on a transceiver change. - Display PAUSE settings in ifconfig.

This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters. These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision.

It is already used in the driver as if it does. r322985: cxgbe(4): Maintain one ifmedia per physical port instead of one per Virtual Interface (VI). All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults.

The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port.

This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters.

This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port. Before this change ifconfig diplayed potentially stale information for ports that were administratively down. - Always recalculate and reapply L1 config on a transceiver change. - Display PAUSE settings in ifconfig.

This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters. These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision.

It is already used in the driver as if it does. r322985: cxgbe(4): Maintain one ifmedia per physical port instead of one per Virtual Interface (VI). All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port.

The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections.

Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults. The congestion channel map, which is still fixed, needs to be tracked separately now. Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering. Disable it by default when running on Intel CPUs. r328420: cxgbe(4): Do not display harmless warning in non-debug builds. r328423: cxgbe(4): Accept old names of a couple of tunables.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port.

This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters.

The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision.

Add variables to track these tunables while here. r322123: cxgbe(4): Avoid a NULL dereference that would occur during module unload if there were problems earlier during attach. r322167: cxgbe(4): Add the T6 and T5 Unified Wire configuration files to the kernel, just like for T4, when the driver is compiled into the kernel. r322425: cxgbe(4): Save the last reported link parameters and compare them with the current state to determine whether to generate a link-state change notification.

This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+).

This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults. The congestion channel map, which is still fixed, needs to be tracked separately now. Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables.

In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering.

This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering.

These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision. These timers are already displayed in microseconds in the sysctl MIB. Add variables to track these tunables while here. r322123: cxgbe(4): Avoid a NULL dereference that would occur during module unload if there were problems earlier during attach. r322167: cxgbe(4): Add the T6 and T5 Unified Wire configuration files to the kernel, just like for T4, when the driver is compiled into the kernel. r322425: cxgbe(4): Save the last reported link parameters and compare them with the current state to determine whether to generate a link-state change notification. This fixes a bug introduced in r321063 that caused the driver to sometimes skip these notifications. r322549: cxgbe/t4_tom: Use correct name for the ISS-valid bit in options2. r322914: cxgbe(4): Dump the mailbox contents in the same format as CH_DUMP_MBOX. r322960: cxgbe(4): Verify that the driver accesses the firmware mailbox in a thread-safe manner. r322962: cxgbe(4): Remove write only variable from t4_port_init. r322964: cxgbe(4): vi_mac_funcs should include the base Ethernet function.

All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults. The congestion channel map, which is still fixed, needs to be tracked separately now. Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering. Disable it by default when running on Intel CPUs. r328420: cxgbe(4): Do not display harmless warning in non-debug builds. r328423: cxgbe(4): Accept old names of a couple of tunables.

The driver sysctls for this continue to work as well. r321103: cxgbe(4): New ioctls to flash bootrom and boot config to the card. r321179: cxgbe/t4_tom: Log more details about the newly ESTABLISHED tid to the trace buffer. r321390: cxgbe(4): Install the firmware bundled with the driver to the card if it doesn't seem to have one. This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters. These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision. These timers are already displayed in microseconds in the sysctl MIB. Add variables to track these tunables while here. r322123: cxgbe(4): Avoid a NULL dereference that would occur during module unload if there were problems earlier during attach. r322167: cxgbe(4): Add the T6 and T5 Unified Wire configuration files to the kernel, just like for T4, when the driver is compiled into the kernel. r322425: cxgbe(4): Save the last reported link parameters and compare them with the current state to determine whether to generate a link-state change notification. This fixes a bug introduced in r321063 that caused the driver to sometimes skip these notifications. r322549: cxgbe/t4_tom: Use correct name for the ISS-valid bit in options2. r322914: cxgbe(4): Dump the mailbox contents in the same format as CH_DUMP_MBOX. r322960: cxgbe(4): Verify that the driver accesses the firmware mailbox in a thread-safe manner. r322962: cxgbe(4): Remove write only variable from t4_port_init. r322964: cxgbe(4): vi_mac_funcs should include the base Ethernet function. It is already used in the driver as if it does. r322985: cxgbe(4): Maintain one ifmedia per physical port instead of one per Virtual Interface (VI). All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults. The congestion channel map, which is still fixed, needs to be tracked separately now. Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering. Disable it by default when running on Intel CPUs. r328420: cxgbe(4): Do not display harmless warning in non-debug builds. r328423: cxgbe(4): Accept old names of a couple of tunables.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port. Before this change ifconfig diplayed potentially stale information for ports that were administratively down. - Always recalculate and reapply L1 config on a transceiver change. - Display PAUSE settings in ifconfig. The driver sysctls for this continue to work as well. r321103: cxgbe(4): New ioctls to flash bootrom and boot config to the card. r321179: cxgbe/t4_tom: Log more details about the newly ESTABLISHED tid to the trace buffer. r321390: cxgbe(4): Install the firmware bundled with the driver to the card if it doesn't seem to have one. This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters. These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision. These timers are already displayed in microseconds in the sysctl MIB. Add variables to track these tunables while here. r322123: cxgbe(4): Avoid a NULL dereference that would occur during module unload if there were problems earlier during attach. r322167: cxgbe(4): Add the T6 and T5 Unified Wire configuration files to the kernel, just like for T4, when the driver is compiled into the kernel. r322425: cxgbe(4): Save the last reported link parameters and compare them with the current state to determine whether to generate a link-state change notification. This fixes a bug introduced in r321063 that caused the driver to sometimes skip these notifications. r322549: cxgbe/t4_tom: Use correct name for the ISS-valid bit in options2. r322914: cxgbe(4): Dump the mailbox contents in the same format as CH_DUMP_MBOX. r322960: cxgbe(4): Verify that the driver accesses the firmware mailbox in a thread-safe manner. r322962: cxgbe(4): Remove write only variable from t4_port_init. r322964: cxgbe(4): vi_mac_funcs should include the base Ethernet function. It is already used in the driver as if it does. r322985: cxgbe(4): Maintain one ifmedia per physical port instead of one per Virtual Interface (VI). All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults. The congestion channel map, which is still fixed, needs to be tracked separately now. Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port. Before this change ifconfig diplayed potentially stale information for ports that were administratively down. - Always recalculate and reapply L1 config on a transceiver change. - Display PAUSE settings in ifconfig.

This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters. These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision.

It is already used in the driver as if it does. r322985: cxgbe(4): Maintain one ifmedia per physical port instead of one per Virtual Interface (VI). All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults.

The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port.

This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters.

This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port. Before this change ifconfig diplayed potentially stale information for ports that were administratively down. - Always recalculate and reapply L1 config on a transceiver change. - Display PAUSE settings in ifconfig.

This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters. These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision.

It is already used in the driver as if it does. r322985: cxgbe(4): Maintain one ifmedia per physical port instead of one per Virtual Interface (VI). All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port. Before this change ifconfig diplayed potentially stale information for ports that were administratively down. - Always recalculate and reapply L1 config on a transceiver change. - Display PAUSE settings in ifconfig. The driver sysctls for this continue to work as well. r321103: cxgbe(4): New ioctls to flash bootrom and boot config to the card. r321179: cxgbe/t4_tom: Log more details about the newly ESTABLISHED tid to the trace buffer. r321390: cxgbe(4): Install the firmware bundled with the driver to the card if it doesn't seem to have one. This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters. These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision. These timers are already displayed in microseconds in the sysctl MIB. Add variables to track these tunables while here. r322123: cxgbe(4): Avoid a NULL dereference that would occur during module unload if there were problems earlier during attach. r322167: cxgbe(4): Add the T6 and T5 Unified Wire configuration files to the kernel, just like for T4, when the driver is compiled into the kernel. r322425: cxgbe(4): Save the last reported link parameters and compare them with the current state to determine whether to generate a link-state change notification. This fixes a bug introduced in r321063 that caused the driver to sometimes skip these notifications. r322549: cxgbe/t4_tom: Use correct name for the ISS-valid bit in options2. r322914: cxgbe(4): Dump the mailbox contents in the same format as CH_DUMP_MBOX. r322960: cxgbe(4): Verify that the driver accesses the firmware mailbox in a thread-safe manner. r322962: cxgbe(4): Remove write only variable from t4_port_init. r322964: cxgbe(4): vi_mac_funcs should include the base Ethernet function. It is already used in the driver as if it does. r322985: cxgbe(4): Maintain one ifmedia per physical port instead of one per Virtual Interface (VI). All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending.

Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults. The congestion channel map, which is still fixed, needs to be tracked separately now. Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering. Disable it by default when running on Intel CPUs. r328420: cxgbe(4): Do not display harmless warning in non-debug builds. r328423: cxgbe(4): Accept old names of a couple of tunables.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port.

This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters.

The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision.

Add variables to track these tunables while here. r322123: cxgbe(4): Avoid a NULL dereference that would occur during module unload if there were problems earlier during attach. r322167: cxgbe(4): Add the T6 and T5 Unified Wire configuration files to the kernel, just like for T4, when the driver is compiled into the kernel. r322425: cxgbe(4): Save the last reported link parameters and compare them with the current state to determine whether to generate a link-state change notification.

Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults.

Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables.

In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering.

This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering.

These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision. These timers are already displayed in microseconds in the sysctl MIB. Add variables to track these tunables while here. r322123: cxgbe(4): Avoid a NULL dereference that would occur during module unload if there were problems earlier during attach. r322167: cxgbe(4): Add the T6 and T5 Unified Wire configuration files to the kernel, just like for T4, when the driver is compiled into the kernel. r322425: cxgbe(4): Save the last reported link parameters and compare them with the current state to determine whether to generate a link-state change notification. This fixes a bug introduced in r321063 that caused the driver to sometimes skip these notifications. r322549: cxgbe/t4_tom: Use correct name for the ISS-valid bit in options2. r322914: cxgbe(4): Dump the mailbox contents in the same format as CH_DUMP_MBOX. r322960: cxgbe(4): Verify that the driver accesses the firmware mailbox in a thread-safe manner. r322962: cxgbe(4): Remove write only variable from t4_port_init. r322964: cxgbe(4): vi_mac_funcs should include the base Ethernet function.

All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults. The congestion channel map, which is still fixed, needs to be tracked separately now. Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering. Disable it by default when running on Intel CPUs. r328420: cxgbe(4): Do not display harmless warning in non-debug builds. r328423: cxgbe(4): Accept old names of a couple of tunables.

The driver sysctls for this continue to work as well. r321103: cxgbe(4): New ioctls to flash bootrom and boot config to the card. r321179: cxgbe/t4_tom: Log more details about the newly ESTABLISHED tid to the trace buffer. r321390: cxgbe(4): Install the firmware bundled with the driver to the card if it doesn't seem to have one. This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters. These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision. These timers are already displayed in microseconds in the sysctl MIB. Add variables to track these tunables while here. r322123: cxgbe(4): Avoid a NULL dereference that would occur during module unload if there were problems earlier during attach. r322167: cxgbe(4): Add the T6 and T5 Unified Wire configuration files to the kernel, just like for T4, when the driver is compiled into the kernel. r322425: cxgbe(4): Save the last reported link parameters and compare them with the current state to determine whether to generate a link-state change notification. This fixes a bug introduced in r321063 that caused the driver to sometimes skip these notifications. r322549: cxgbe/t4_tom: Use correct name for the ISS-valid bit in options2. r322914: cxgbe(4): Dump the mailbox contents in the same format as CH_DUMP_MBOX. r322960: cxgbe(4): Verify that the driver accesses the firmware mailbox in a thread-safe manner. r322962: cxgbe(4): Remove write only variable from t4_port_init. r322964: cxgbe(4): vi_mac_funcs should include the base Ethernet function. It is already used in the driver as if it does. r322985: cxgbe(4): Maintain one ifmedia per physical port instead of one per Virtual Interface (VI). All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults. The congestion channel map, which is still fixed, needs to be tracked separately now. Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering. Disable it by default when running on Intel CPUs. r328420: cxgbe(4): Do not display harmless warning in non-debug builds. r328423: cxgbe(4): Accept old names of a couple of tunables.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port. Before this change ifconfig diplayed potentially stale information for ports that were administratively down. - Always recalculate and reapply L1 config on a transceiver change. - Display PAUSE settings in ifconfig. The driver sysctls for this continue to work as well. r321103: cxgbe(4): New ioctls to flash bootrom and boot config to the card. r321179: cxgbe/t4_tom: Log more details about the newly ESTABLISHED tid to the trace buffer. r321390: cxgbe(4): Install the firmware bundled with the driver to the card if it doesn't seem to have one. This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters. These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision. These timers are already displayed in microseconds in the sysctl MIB. Add variables to track these tunables while here. r322123: cxgbe(4): Avoid a NULL dereference that would occur during module unload if there were problems earlier during attach. r322167: cxgbe(4): Add the T6 and T5 Unified Wire configuration files to the kernel, just like for T4, when the driver is compiled into the kernel. r322425: cxgbe(4): Save the last reported link parameters and compare them with the current state to determine whether to generate a link-state change notification. This fixes a bug introduced in r321063 that caused the driver to sometimes skip these notifications. r322549: cxgbe/t4_tom: Use correct name for the ISS-valid bit in options2. r322914: cxgbe(4): Dump the mailbox contents in the same format as CH_DUMP_MBOX. r322960: cxgbe(4): Verify that the driver accesses the firmware mailbox in a thread-safe manner. r322962: cxgbe(4): Remove write only variable from t4_port_init. r322964: cxgbe(4): vi_mac_funcs should include the base Ethernet function. It is already used in the driver as if it does. r322985: cxgbe(4): Maintain one ifmedia per physical port instead of one per Virtual Interface (VI). All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults. The congestion channel map, which is still fixed, needs to be tracked separately now. Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port. Before this change ifconfig diplayed potentially stale information for ports that were administratively down. - Always recalculate and reapply L1 config on a transceiver change. - Display PAUSE settings in ifconfig. The driver sysctls for this continue to work as well. r321103: cxgbe(4): New ioctls to flash bootrom and boot config to the card. r321179: cxgbe/t4_tom: Log more details about the newly ESTABLISHED tid to the trace buffer. r321390: cxgbe(4): Install the firmware bundled with the driver to the card if it doesn't seem to have one. This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters. These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision.

It is already used in the driver as if it does. r322985: cxgbe(4): Maintain one ifmedia per physical port instead of one per Virtual Interface (VI). All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults.

Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port.

This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters.

The ioctl can be used to collect the chip's internal state in a compressed dump file.

This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port. Before this change ifconfig diplayed potentially stale information for ports that were administratively down. - Always recalculate and reapply L1 config on a transceiver change. - Display PAUSE settings in ifconfig.

This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters. These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file.

It is already used in the driver as if it does. r322985: cxgbe(4): Maintain one ifmedia per physical port instead of one per Virtual Interface (VI). All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port.

The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections.

Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults. The congestion channel map, which is still fixed, needs to be tracked separately now. Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering. Disable it by default when running on Intel CPUs. r328420: cxgbe(4): Do not display harmless warning in non-debug builds. r328423: cxgbe(4): Accept old names of a couple of tunables.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port.

This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters.

The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision.

Add variables to track these tunables while here. r322123: cxgbe(4): Avoid a NULL dereference that would occur during module unload if there were problems earlier during attach. r322167: cxgbe(4): Add the T6 and T5 Unified Wire configuration files to the kernel, just like for T4, when the driver is compiled into the kernel. r322425: cxgbe(4): Save the last reported link parameters and compare them with the current state to determine whether to generate a link-state change notification.

Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults.

Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables.

In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering.

This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering.

These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision. These timers are already displayed in microseconds in the sysctl MIB. Add variables to track these tunables while here. r322123: cxgbe(4): Avoid a NULL dereference that would occur during module unload if there were problems earlier during attach. r322167: cxgbe(4): Add the T6 and T5 Unified Wire configuration files to the kernel, just like for T4, when the driver is compiled into the kernel. r322425: cxgbe(4): Save the last reported link parameters and compare them with the current state to determine whether to generate a link-state change notification. This fixes a bug introduced in r321063 that caused the driver to sometimes skip these notifications. r322549: cxgbe/t4_tom: Use correct name for the ISS-valid bit in options2. r322914: cxgbe(4): Dump the mailbox contents in the same format as CH_DUMP_MBOX. r322960: cxgbe(4): Verify that the driver accesses the firmware mailbox in a thread-safe manner. r322962: cxgbe(4): Remove write only variable from t4_port_init. r322964: cxgbe(4): vi_mac_funcs should include the base Ethernet function. It is already used in the driver as if it does. r322985: cxgbe(4): Maintain one ifmedia per physical port instead of one per Virtual Interface (VI). All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults. The congestion channel map, which is still fixed, needs to be tracked separately now. Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering. Disable it by default when running on Intel CPUs. r328420: cxgbe(4): Do not display harmless warning in non-debug builds. r328423: cxgbe(4): Accept old names of a couple of tunables.

The driver sysctls for this continue to work as well. r321103: cxgbe(4): New ioctls to flash bootrom and boot config to the card. r321179: cxgbe/t4_tom: Log more details about the newly ESTABLISHED tid to the trace buffer. r321390: cxgbe(4): Install the firmware bundled with the driver to the card if it doesn't seem to have one. This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters. These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision. These timers are already displayed in microseconds in the sysctl MIB. Add variables to track these tunables while here. r322123: cxgbe(4): Avoid a NULL dereference that would occur during module unload if there were problems earlier during attach. r322167: cxgbe(4): Add the T6 and T5 Unified Wire configuration files to the kernel, just like for T4, when the driver is compiled into the kernel. r322425: cxgbe(4): Save the last reported link parameters and compare them with the current state to determine whether to generate a link-state change notification. This fixes a bug introduced in r321063 that caused the driver to sometimes skip these notifications. r322549: cxgbe/t4_tom: Use correct name for the ISS-valid bit in options2. r322914: cxgbe(4): Dump the mailbox contents in the same format as CH_DUMP_MBOX. r322960: cxgbe(4): Verify that the driver accesses the firmware mailbox in a thread-safe manner. r322962: cxgbe(4): Remove write only variable from t4_port_init. r322964: cxgbe(4): vi_mac_funcs should include the base Ethernet function. It is already used in the driver as if it does. r322985: cxgbe(4): Maintain one ifmedia per physical port instead of one per Virtual Interface (VI). All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults. The congestion channel map, which is still fixed, needs to be tracked separately now. Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering. Disable it by default when running on Intel CPUs. r328420: cxgbe(4): Do not display harmless warning in non-debug builds. r328423: cxgbe(4): Accept old names of a couple of tunables.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port. Before this change ifconfig diplayed potentially stale information for ports that were administratively down. - Always recalculate and reapply L1 config on a transceiver change. - Display PAUSE settings in ifconfig. The driver sysctls for this continue to work as well. r321103: cxgbe(4): New ioctls to flash bootrom and boot config to the card. r321179: cxgbe/t4_tom: Log more details about the newly ESTABLISHED tid to the trace buffer. r321390: cxgbe(4): Install the firmware bundled with the driver to the card if it doesn't seem to have one. This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters. These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision. These timers are already displayed in microseconds in the sysctl MIB. Add variables to track these tunables while here. r322123: cxgbe(4): Avoid a NULL dereference that would occur during module unload if there were problems earlier during attach. r322167: cxgbe(4): Add the T6 and T5 Unified Wire configuration files to the kernel, just like for T4, when the driver is compiled into the kernel. r322425: cxgbe(4): Save the last reported link parameters and compare them with the current state to determine whether to generate a link-state change notification. This fixes a bug introduced in r321063 that caused the driver to sometimes skip these notifications. r322549: cxgbe/t4_tom: Use correct name for the ISS-valid bit in options2. r322914: cxgbe(4): Dump the mailbox contents in the same format as CH_DUMP_MBOX. r322960: cxgbe(4): Verify that the driver accesses the firmware mailbox in a thread-safe manner. r322962: cxgbe(4): Remove write only variable from t4_port_init. r322964: cxgbe(4): vi_mac_funcs should include the base Ethernet function. It is already used in the driver as if it does. r322985: cxgbe(4): Maintain one ifmedia per physical port instead of one per Virtual Interface (VI). All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults. The congestion channel map, which is still fixed, needs to be tracked separately now. Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port. Before this change ifconfig diplayed potentially stale information for ports that were administratively down. - Always recalculate and reapply L1 config on a transceiver change. - Display PAUSE settings in ifconfig. The driver sysctls for this continue to work as well. r321103: cxgbe(4): New ioctls to flash bootrom and boot config to the card. r321179: cxgbe/t4_tom: Log more details about the newly ESTABLISHED tid to the trace buffer. r321390: cxgbe(4): Install the firmware bundled with the driver to the card if it doesn't seem to have one. This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters. These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision.

It is already used in the driver as if it does. r322985: cxgbe(4): Maintain one ifmedia per physical port instead of one per Virtual Interface (VI). All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults.

Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port.

This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters.

The ioctl can be used to collect the chip's internal state in a compressed dump file.

This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port. Before this change ifconfig diplayed potentially stale information for ports that were administratively down. - Always recalculate and reapply L1 config on a transceiver change. - Display PAUSE settings in ifconfig.

This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters. These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file.

It is already used in the driver as if it does. r322985: cxgbe(4): Maintain one ifmedia per physical port instead of one per Virtual Interface (VI). All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port.

The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections.

Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults. The congestion channel map, which is still fixed, needs to be tracked separately now. Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering. Disable it by default when running on Intel CPUs. r328420: cxgbe(4): Do not display harmless warning in non-debug builds. r328423: cxgbe(4): Accept old names of a couple of tunables.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port.

This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters.

The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision.

Add variables to track these tunables while here. r322123: cxgbe(4): Avoid a NULL dereference that would occur during module unload if there were problems earlier during attach. r322167: cxgbe(4): Add the T6 and T5 Unified Wire configuration files to the kernel, just like for T4, when the driver is compiled into the kernel. r322425: cxgbe(4): Save the last reported link parameters and compare them with the current state to determine whether to generate a link-state change notification.

Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults.

Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables.

In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering.

This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering.

These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision. These timers are already displayed in microseconds in the sysctl MIB. Add variables to track these tunables while here. r322123: cxgbe(4): Avoid a NULL dereference that would occur during module unload if there were problems earlier during attach. r322167: cxgbe(4): Add the T6 and T5 Unified Wire configuration files to the kernel, just like for T4, when the driver is compiled into the kernel. r322425: cxgbe(4): Save the last reported link parameters and compare them with the current state to determine whether to generate a link-state change notification. This fixes a bug introduced in r321063 that caused the driver to sometimes skip these notifications. r322549: cxgbe/t4_tom: Use correct name for the ISS-valid bit in options2. r322914: cxgbe(4): Dump the mailbox contents in the same format as CH_DUMP_MBOX. r322960: cxgbe(4): Verify that the driver accesses the firmware mailbox in a thread-safe manner. r322962: cxgbe(4): Remove write only variable from t4_port_init. r322964: cxgbe(4): vi_mac_funcs should include the base Ethernet function.

All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults. The congestion channel map, which is still fixed, needs to be tracked separately now. Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering. Disable it by default when running on Intel CPUs. r328420: cxgbe(4): Do not display harmless warning in non-debug builds. r328423: cxgbe(4): Accept old names of a couple of tunables.

The driver sysctls for this continue to work as well. r321103: cxgbe(4): New ioctls to flash bootrom and boot config to the card. r321179: cxgbe/t4_tom: Log more details about the newly ESTABLISHED tid to the trace buffer. r321390: cxgbe(4): Install the firmware bundled with the driver to the card if it doesn't seem to have one. This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters. These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision. These timers are already displayed in microseconds in the sysctl MIB. Add variables to track these tunables while here. r322123: cxgbe(4): Avoid a NULL dereference that would occur during module unload if there were problems earlier during attach. r322167: cxgbe(4): Add the T6 and T5 Unified Wire configuration files to the kernel, just like for T4, when the driver is compiled into the kernel. r322425: cxgbe(4): Save the last reported link parameters and compare them with the current state to determine whether to generate a link-state change notification. This fixes a bug introduced in r321063 that caused the driver to sometimes skip these notifications. r322549: cxgbe/t4_tom: Use correct name for the ISS-valid bit in options2. r322914: cxgbe(4): Dump the mailbox contents in the same format as CH_DUMP_MBOX. r322960: cxgbe(4): Verify that the driver accesses the firmware mailbox in a thread-safe manner. r322962: cxgbe(4): Remove write only variable from t4_port_init. r322964: cxgbe(4): vi_mac_funcs should include the base Ethernet function. It is already used in the driver as if it does. r322985: cxgbe(4): Maintain one ifmedia per physical port instead of one per Virtual Interface (VI). All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults. The congestion channel map, which is still fixed, needs to be tracked separately now. Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering. Disable it by default when running on Intel CPUs. r328420: cxgbe(4): Do not display harmless warning in non-debug builds. r328423: cxgbe(4): Accept old names of a couple of tunables.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port. Before this change ifconfig diplayed potentially stale information for ports that were administratively down. - Always recalculate and reapply L1 config on a transceiver change. - Display PAUSE settings in ifconfig. The driver sysctls for this continue to work as well. r321103: cxgbe(4): New ioctls to flash bootrom and boot config to the card. r321179: cxgbe/t4_tom: Log more details about the newly ESTABLISHED tid to the trace buffer. r321390: cxgbe(4): Install the firmware bundled with the driver to the card if it doesn't seem to have one. This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters. These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision. These timers are already displayed in microseconds in the sysctl MIB. Add variables to track these tunables while here. r322123: cxgbe(4): Avoid a NULL dereference that would occur during module unload if there were problems earlier during attach. r322167: cxgbe(4): Add the T6 and T5 Unified Wire configuration files to the kernel, just like for T4, when the driver is compiled into the kernel. r322425: cxgbe(4): Save the last reported link parameters and compare them with the current state to determine whether to generate a link-state change notification. This fixes a bug introduced in r321063 that caused the driver to sometimes skip these notifications. r322549: cxgbe/t4_tom: Use correct name for the ISS-valid bit in options2. r322914: cxgbe(4): Dump the mailbox contents in the same format as CH_DUMP_MBOX. r322960: cxgbe(4): Verify that the driver accesses the firmware mailbox in a thread-safe manner. r322962: cxgbe(4): Remove write only variable from t4_port_init. r322964: cxgbe(4): vi_mac_funcs should include the base Ethernet function. It is already used in the driver as if it does. r322985: cxgbe(4): Maintain one ifmedia per physical port instead of one per Virtual Interface (VI). All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults. The congestion channel map, which is still fixed, needs to be tracked separately now. Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port. Before this change ifconfig diplayed potentially stale information for ports that were administratively down. - Always recalculate and reapply L1 config on a transceiver change. - Display PAUSE settings in ifconfig. The driver sysctls for this continue to work as well. r321103: cxgbe(4): New ioctls to flash bootrom and boot config to the card. r321179: cxgbe/t4_tom: Log more details about the newly ESTABLISHED tid to the trace buffer. r321390: cxgbe(4): Install the firmware bundled with the driver to the card if it doesn't seem to have one. This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters. These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision.

It is already used in the driver as if it does. r322985: cxgbe(4): Maintain one ifmedia per physical port instead of one per Virtual Interface (VI). All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults.

Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists.

The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port. Before this change ifconfig diplayed potentially stale information for ports that were administratively down. - Always recalculate and reapply L1 config on a transceiver change. - Display PAUSE settings in ifconfig.

This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters. These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file.

It is already used in the driver as if it does. r322985: cxgbe(4): Maintain one ifmedia per physical port instead of one per Virtual Interface (VI). All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port.

The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections.

Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults. The congestion channel map, which is still fixed, needs to be tracked separately now. Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering. Disable it by default when running on Intel CPUs. r328420: cxgbe(4): Do not display harmless warning in non-debug builds. r328423: cxgbe(4): Accept old names of a couple of tunables.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port.

This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters.

The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision.

Add variables to track these tunables while here. r322123: cxgbe(4): Avoid a NULL dereference that would occur during module unload if there were problems earlier during attach. r322167: cxgbe(4): Add the T6 and T5 Unified Wire configuration files to the kernel, just like for T4, when the driver is compiled into the kernel. r322425: cxgbe(4): Save the last reported link parameters and compare them with the current state to determine whether to generate a link-state change notification.

Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults.

Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables.

In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering.

This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering.

These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision. These timers are already displayed in microseconds in the sysctl MIB. Add variables to track these tunables while here. r322123: cxgbe(4): Avoid a NULL dereference that would occur during module unload if there were problems earlier during attach. r322167: cxgbe(4): Add the T6 and T5 Unified Wire configuration files to the kernel, just like for T4, when the driver is compiled into the kernel. r322425: cxgbe(4): Save the last reported link parameters and compare them with the current state to determine whether to generate a link-state change notification. This fixes a bug introduced in r321063 that caused the driver to sometimes skip these notifications. r322549: cxgbe/t4_tom: Use correct name for the ISS-valid bit in options2. r322914: cxgbe(4): Dump the mailbox contents in the same format as CH_DUMP_MBOX. r322960: cxgbe(4): Verify that the driver accesses the firmware mailbox in a thread-safe manner. r322962: cxgbe(4): Remove write only variable from t4_port_init. r322964: cxgbe(4): vi_mac_funcs should include the base Ethernet function.

All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults. The congestion channel map, which is still fixed, needs to be tracked separately now. Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering. Disable it by default when running on Intel CPUs. r328420: cxgbe(4): Do not display harmless warning in non-debug builds. r328423: cxgbe(4): Accept old names of a couple of tunables.

The driver sysctls for this continue to work as well. r321103: cxgbe(4): New ioctls to flash bootrom and boot config to the card. r321179: cxgbe/t4_tom: Log more details about the newly ESTABLISHED tid to the trace buffer. r321390: cxgbe(4): Install the firmware bundled with the driver to the card if it doesn't seem to have one. This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters. These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision. These timers are already displayed in microseconds in the sysctl MIB. Add variables to track these tunables while here. r322123: cxgbe(4): Avoid a NULL dereference that would occur during module unload if there were problems earlier during attach. r322167: cxgbe(4): Add the T6 and T5 Unified Wire configuration files to the kernel, just like for T4, when the driver is compiled into the kernel. r322425: cxgbe(4): Save the last reported link parameters and compare them with the current state to determine whether to generate a link-state change notification. This fixes a bug introduced in r321063 that caused the driver to sometimes skip these notifications. r322549: cxgbe/t4_tom: Use correct name for the ISS-valid bit in options2. r322914: cxgbe(4): Dump the mailbox contents in the same format as CH_DUMP_MBOX. r322960: cxgbe(4): Verify that the driver accesses the firmware mailbox in a thread-safe manner. r322962: cxgbe(4): Remove write only variable from t4_port_init. r322964: cxgbe(4): vi_mac_funcs should include the base Ethernet function. It is already used in the driver as if it does. r322985: cxgbe(4): Maintain one ifmedia per physical port instead of one per Virtual Interface (VI). All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults. The congestion channel map, which is still fixed, needs to be tracked separately now. Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering. Disable it by default when running on Intel CPUs. r328420: cxgbe(4): Do not display harmless warning in non-debug builds. r328423: cxgbe(4): Accept old names of a couple of tunables.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port. Before this change ifconfig diplayed potentially stale information for ports that were administratively down. - Always recalculate and reapply L1 config on a transceiver change. - Display PAUSE settings in ifconfig. The driver sysctls for this continue to work as well. r321103: cxgbe(4): New ioctls to flash bootrom and boot config to the card. r321179: cxgbe/t4_tom: Log more details about the newly ESTABLISHED tid to the trace buffer. r321390: cxgbe(4): Install the firmware bundled with the driver to the card if it doesn't seem to have one. This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters. These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision. These timers are already displayed in microseconds in the sysctl MIB. Add variables to track these tunables while here. r322123: cxgbe(4): Avoid a NULL dereference that would occur during module unload if there were problems earlier during attach. r322167: cxgbe(4): Add the T6 and T5 Unified Wire configuration files to the kernel, just like for T4, when the driver is compiled into the kernel. r322425: cxgbe(4): Save the last reported link parameters and compare them with the current state to determine whether to generate a link-state change notification. This fixes a bug introduced in r321063 that caused the driver to sometimes skip these notifications. r322549: cxgbe/t4_tom: Use correct name for the ISS-valid bit in options2. r322914: cxgbe(4): Dump the mailbox contents in the same format as CH_DUMP_MBOX. r322960: cxgbe(4): Verify that the driver accesses the firmware mailbox in a thread-safe manner. r322962: cxgbe(4): Remove write only variable from t4_port_init. r322964: cxgbe(4): vi_mac_funcs should include the base Ethernet function. It is already used in the driver as if it does. r322985: cxgbe(4): Maintain one ifmedia per physical port instead of one per Virtual Interface (VI). All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults. The congestion channel map, which is still fixed, needs to be tracked separately now. Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port. Before this change ifconfig diplayed potentially stale information for ports that were administratively down. - Always recalculate and reapply L1 config on a transceiver change. - Display PAUSE settings in ifconfig. The driver sysctls for this continue to work as well. r321103: cxgbe(4): New ioctls to flash bootrom and boot config to the card. r321179: cxgbe/t4_tom: Log more details about the newly ESTABLISHED tid to the trace buffer. r321390: cxgbe(4): Install the firmware bundled with the driver to the card if it doesn't seem to have one. This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters. These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision.

It is already used in the driver as if it does. r322985: cxgbe(4): Maintain one ifmedia per physical port instead of one per Virtual Interface (VI). All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults.

Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port.

This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters.

The ioctl can be used to collect the chip's internal state in a compressed dump file.

This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port. Before this change ifconfig diplayed potentially stale information for ports that were administratively down. - Always recalculate and reapply L1 config on a transceiver change. - Display PAUSE settings in ifconfig.

This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters. These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file.

It is already used in the driver as if it does. r322985: cxgbe(4): Maintain one ifmedia per physical port instead of one per Virtual Interface (VI). All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port.

The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections.

Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults. The congestion channel map, which is still fixed, needs to be tracked separately now. Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering. Disable it by default when running on Intel CPUs. r328420: cxgbe(4): Do not display harmless warning in non-debug builds. r328423: cxgbe(4): Accept old names of a couple of tunables.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port.

This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters.

The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision.

Add variables to track these tunables while here. r322123: cxgbe(4): Avoid a NULL dereference that would occur during module unload if there were problems earlier during attach. r322167: cxgbe(4): Add the T6 and T5 Unified Wire configuration files to the kernel, just like for T4, when the driver is compiled into the kernel. r322425: cxgbe(4): Save the last reported link parameters and compare them with the current state to determine whether to generate a link-state change notification.

This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering.

These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision. These timers are already displayed in microseconds in the sysctl MIB. Add variables to track these tunables while here. r322123: cxgbe(4): Avoid a NULL dereference that would occur during module unload if there were problems earlier during attach. r322167: cxgbe(4): Add the T6 and T5 Unified Wire configuration files to the kernel, just like for T4, when the driver is compiled into the kernel. r322425: cxgbe(4): Save the last reported link parameters and compare them with the current state to determine whether to generate a link-state change notification. This fixes a bug introduced in r321063 that caused the driver to sometimes skip these notifications. r322549: cxgbe/t4_tom: Use correct name for the ISS-valid bit in options2. r322914: cxgbe(4): Dump the mailbox contents in the same format as CH_DUMP_MBOX. r322960: cxgbe(4): Verify that the driver accesses the firmware mailbox in a thread-safe manner. r322962: cxgbe(4): Remove write only variable from t4_port_init. r322964: cxgbe(4): vi_mac_funcs should include the base Ethernet function.

All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults. The congestion channel map, which is still fixed, needs to be tracked separately now. Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering. Disable it by default when running on Intel CPUs. r328420: cxgbe(4): Do not display harmless warning in non-debug builds. r328423: cxgbe(4): Accept old names of a couple of tunables.

The driver sysctls for this continue to work as well. r321103: cxgbe(4): New ioctls to flash bootrom and boot config to the card. r321179: cxgbe/t4_tom: Log more details about the newly ESTABLISHED tid to the trace buffer. r321390: cxgbe(4): Install the firmware bundled with the driver to the card if it doesn't seem to have one. This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters. These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision. These timers are already displayed in microseconds in the sysctl MIB. Add variables to track these tunables while here. r322123: cxgbe(4): Avoid a NULL dereference that would occur during module unload if there were problems earlier during attach. r322167: cxgbe(4): Add the T6 and T5 Unified Wire configuration files to the kernel, just like for T4, when the driver is compiled into the kernel. r322425: cxgbe(4): Save the last reported link parameters and compare them with the current state to determine whether to generate a link-state change notification. This fixes a bug introduced in r321063 that caused the driver to sometimes skip these notifications. r322549: cxgbe/t4_tom: Use correct name for the ISS-valid bit in options2. r322914: cxgbe(4): Dump the mailbox contents in the same format as CH_DUMP_MBOX. r322960: cxgbe(4): Verify that the driver accesses the firmware mailbox in a thread-safe manner. r322962: cxgbe(4): Remove write only variable from t4_port_init. r322964: cxgbe(4): vi_mac_funcs should include the base Ethernet function. It is already used in the driver as if it does. r322985: cxgbe(4): Maintain one ifmedia per physical port instead of one per Virtual Interface (VI). All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults. The congestion channel map, which is still fixed, needs to be tracked separately now. Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering. Disable it by default when running on Intel CPUs. r328420: cxgbe(4): Do not display harmless warning in non-debug builds. r328423: cxgbe(4): Accept old names of a couple of tunables.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port. Before this change ifconfig diplayed potentially stale information for ports that were administratively down. - Always recalculate and reapply L1 config on a transceiver change. - Display PAUSE settings in ifconfig. The driver sysctls for this continue to work as well. r321103: cxgbe(4): New ioctls to flash bootrom and boot config to the card. r321179: cxgbe/t4_tom: Log more details about the newly ESTABLISHED tid to the trace buffer. r321390: cxgbe(4): Install the firmware bundled with the driver to the card if it doesn't seem to have one. This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters. These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision. These timers are already displayed in microseconds in the sysctl MIB. Add variables to track these tunables while here. r322123: cxgbe(4): Avoid a NULL dereference that would occur during module unload if there were problems earlier during attach. r322167: cxgbe(4): Add the T6 and T5 Unified Wire configuration files to the kernel, just like for T4, when the driver is compiled into the kernel. r322425: cxgbe(4): Save the last reported link parameters and compare them with the current state to determine whether to generate a link-state change notification. This fixes a bug introduced in r321063 that caused the driver to sometimes skip these notifications. r322549: cxgbe/t4_tom: Use correct name for the ISS-valid bit in options2. r322914: cxgbe(4): Dump the mailbox contents in the same format as CH_DUMP_MBOX. r322960: cxgbe(4): Verify that the driver accesses the firmware mailbox in a thread-safe manner. r322962: cxgbe(4): Remove write only variable from t4_port_init. r322964: cxgbe(4): vi_mac_funcs should include the base Ethernet function. It is already used in the driver as if it does. r322985: cxgbe(4): Maintain one ifmedia per physical port instead of one per Virtual Interface (VI). All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults. The congestion channel map, which is still fixed, needs to be tracked separately now. Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port. Before this change ifconfig diplayed potentially stale information for ports that were administratively down. - Always recalculate and reapply L1 config on a transceiver change. - Display PAUSE settings in ifconfig. The driver sysctls for this continue to work as well. r321103: cxgbe(4): New ioctls to flash bootrom and boot config to the card. r321179: cxgbe/t4_tom: Log more details about the newly ESTABLISHED tid to the trace buffer. r321390: cxgbe(4): Install the firmware bundled with the driver to the card if it doesn't seem to have one. This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters. These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision.

It is already used in the driver as if it does. r322985: cxgbe(4): Maintain one ifmedia per physical port instead of one per Virtual Interface (VI). All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults.

Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port.

This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters.

The ioctl can be used to collect the chip's internal state in a compressed dump file.

This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port. Before this change ifconfig diplayed potentially stale information for ports that were administratively down. - Always recalculate and reapply L1 config on a transceiver change. - Display PAUSE settings in ifconfig.

This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters. These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file.

It is already used in the driver as if it does. r322985: cxgbe(4): Maintain one ifmedia per physical port instead of one per Virtual Interface (VI). All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port.

The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections.

Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults. The congestion channel map, which is still fixed, needs to be tracked separately now. Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering. Disable it by default when running on Intel CPUs. r328420: cxgbe(4): Do not display harmless warning in non-debug builds. r328423: cxgbe(4): Accept old names of a couple of tunables.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port.

This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters.

The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision.

Add variables to track these tunables while here. r322123: cxgbe(4): Avoid a NULL dereference that would occur during module unload if there were problems earlier during attach. r322167: cxgbe(4): Add the T6 and T5 Unified Wire configuration files to the kernel, just like for T4, when the driver is compiled into the kernel. r322425: cxgbe(4): Save the last reported link parameters and compare them with the current state to determine whether to generate a link-state change notification.

Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults.

Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables.

In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering.

This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering.

These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision. These timers are already displayed in microseconds in the sysctl MIB. Add variables to track these tunables while here. r322123: cxgbe(4): Avoid a NULL dereference that would occur during module unload if there were problems earlier during attach. r322167: cxgbe(4): Add the T6 and T5 Unified Wire configuration files to the kernel, just like for T4, when the driver is compiled into the kernel. r322425: cxgbe(4): Save the last reported link parameters and compare them with the current state to determine whether to generate a link-state change notification. This fixes a bug introduced in r321063 that caused the driver to sometimes skip these notifications. r322549: cxgbe/t4_tom: Use correct name for the ISS-valid bit in options2. r322914: cxgbe(4): Dump the mailbox contents in the same format as CH_DUMP_MBOX. r322960: cxgbe(4): Verify that the driver accesses the firmware mailbox in a thread-safe manner. r322962: cxgbe(4): Remove write only variable from t4_port_init. r322964: cxgbe(4): vi_mac_funcs should include the base Ethernet function.

All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults. The congestion channel map, which is still fixed, needs to be tracked separately now. Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering. Disable it by default when running on Intel CPUs. r328420: cxgbe(4): Do not display harmless warning in non-debug builds. r328423: cxgbe(4): Accept old names of a couple of tunables.

The driver sysctls for this continue to work as well. r321103: cxgbe(4): New ioctls to flash bootrom and boot config to the card. r321179: cxgbe/t4_tom: Log more details about the newly ESTABLISHED tid to the trace buffer. r321390: cxgbe(4): Install the firmware bundled with the driver to the card if it doesn't seem to have one. This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters. These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision. These timers are already displayed in microseconds in the sysctl MIB. Add variables to track these tunables while here. r322123: cxgbe(4): Avoid a NULL dereference that would occur during module unload if there were problems earlier during attach. r322167: cxgbe(4): Add the T6 and T5 Unified Wire configuration files to the kernel, just like for T4, when the driver is compiled into the kernel. r322425: cxgbe(4): Save the last reported link parameters and compare them with the current state to determine whether to generate a link-state change notification. This fixes a bug introduced in r321063 that caused the driver to sometimes skip these notifications. r322549: cxgbe/t4_tom: Use correct name for the ISS-valid bit in options2. r322914: cxgbe(4): Dump the mailbox contents in the same format as CH_DUMP_MBOX. r322960: cxgbe(4): Verify that the driver accesses the firmware mailbox in a thread-safe manner. r322962: cxgbe(4): Remove write only variable from t4_port_init. r322964: cxgbe(4): vi_mac_funcs should include the base Ethernet function. It is already used in the driver as if it does. r322985: cxgbe(4): Maintain one ifmedia per physical port instead of one per Virtual Interface (VI). All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults. The congestion channel map, which is still fixed, needs to be tracked separately now. Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering. Disable it by default when running on Intel CPUs. r328420: cxgbe(4): Do not display harmless warning in non-debug builds. r328423: cxgbe(4): Accept old names of a couple of tunables.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port.

This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters. These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision.

This fixes a bug introduced in r321063 that caused the driver to sometimes skip these notifications. r322549: cxgbe/t4_tom: Use correct name for the ISS-valid bit in options2. r322914: cxgbe(4): Dump the mailbox contents in the same format as CH_DUMP_MBOX. r322960: cxgbe(4): Verify that the driver accesses the firmware mailbox in a thread-safe manner. r322962: cxgbe(4): Remove write only variable from t4_port_init. r322964: cxgbe(4): vi_mac_funcs should include the base Ethernet function. It is already used in the driver as if it does. r322985: cxgbe(4): Maintain one ifmedia per physical port instead of one per Virtual Interface (VI). All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults. The congestion channel map, which is still fixed, needs to be tracked separately now. Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port. Before this change ifconfig diplayed potentially stale information for ports that were administratively down. - Always recalculate and reapply L1 config on a transceiver change. - Display PAUSE settings in ifconfig. The driver sysctls for this continue to work as well. r321103: cxgbe(4): New ioctls to flash bootrom and boot config to the card. r321179: cxgbe/t4_tom: Log more details about the newly ESTABLISHED tid to the trace buffer. r321390: cxgbe(4): Install the firmware bundled with the driver to the card if it doesn't seem to have one. This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters. These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision.

It is already used in the driver as if it does. r322985: cxgbe(4): Maintain one ifmedia per physical port instead of one per Virtual Interface (VI). All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults.

Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port.

This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters.

The ioctl can be used to collect the chip's internal state in a compressed dump file.

This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port. Before this change ifconfig diplayed potentially stale information for ports that were administratively down. - Always recalculate and reapply L1 config on a transceiver change. - Display PAUSE settings in ifconfig.

This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters. These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file.

It is already used in the driver as if it does. r322985: cxgbe(4): Maintain one ifmedia per physical port instead of one per Virtual Interface (VI). All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port.

The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections.

Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults. The congestion channel map, which is still fixed, needs to be tracked separately now. Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering. Disable it by default when running on Intel CPUs. r328420: cxgbe(4): Do not display harmless warning in non-debug builds. r328423: cxgbe(4): Accept old names of a couple of tunables.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port.

This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters.

The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision.

Add variables to track these tunables while here. r322123: cxgbe(4): Avoid a NULL dereference that would occur during module unload if there were problems earlier during attach. r322167: cxgbe(4): Add the T6 and T5 Unified Wire configuration files to the kernel, just like for T4, when the driver is compiled into the kernel. r322425: cxgbe(4): Save the last reported link parameters and compare them with the current state to determine whether to generate a link-state change notification.

Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults.

Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables.

In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering.

This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering.

These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision. These timers are already displayed in microseconds in the sysctl MIB. Add variables to track these tunables while here. r322123: cxgbe(4): Avoid a NULL dereference that would occur during module unload if there were problems earlier during attach. r322167: cxgbe(4): Add the T6 and T5 Unified Wire configuration files to the kernel, just like for T4, when the driver is compiled into the kernel. r322425: cxgbe(4): Save the last reported link parameters and compare them with the current state to determine whether to generate a link-state change notification. This fixes a bug introduced in r321063 that caused the driver to sometimes skip these notifications. r322549: cxgbe/t4_tom: Use correct name for the ISS-valid bit in options2. r322914: cxgbe(4): Dump the mailbox contents in the same format as CH_DUMP_MBOX. r322960: cxgbe(4): Verify that the driver accesses the firmware mailbox in a thread-safe manner. r322962: cxgbe(4): Remove write only variable from t4_port_init. r322964: cxgbe(4): vi_mac_funcs should include the base Ethernet function.

All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults. The congestion channel map, which is still fixed, needs to be tracked separately now. Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering. Disable it by default when running on Intel CPUs. r328420: cxgbe(4): Do not display harmless warning in non-debug builds. r328423: cxgbe(4): Accept old names of a couple of tunables.

The driver sysctls for this continue to work as well. r321103: cxgbe(4): New ioctls to flash bootrom and boot config to the card. r321179: cxgbe/t4_tom: Log more details about the newly ESTABLISHED tid to the trace buffer. r321390: cxgbe(4): Install the firmware bundled with the driver to the card if it doesn't seem to have one. This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters. These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision. These timers are already displayed in microseconds in the sysctl MIB. Add variables to track these tunables while here. r322123: cxgbe(4): Avoid a NULL dereference that would occur during module unload if there were problems earlier during attach. r322167: cxgbe(4): Add the T6 and T5 Unified Wire configuration files to the kernel, just like for T4, when the driver is compiled into the kernel. r322425: cxgbe(4): Save the last reported link parameters and compare them with the current state to determine whether to generate a link-state change notification. This fixes a bug introduced in r321063 that caused the driver to sometimes skip these notifications. r322549: cxgbe/t4_tom: Use correct name for the ISS-valid bit in options2. r322914: cxgbe(4): Dump the mailbox contents in the same format as CH_DUMP_MBOX. r322960: cxgbe(4): Verify that the driver accesses the firmware mailbox in a thread-safe manner. r322962: cxgbe(4): Remove write only variable from t4_port_init. r322964: cxgbe(4): vi_mac_funcs should include the base Ethernet function. It is already used in the driver as if it does. r322985: cxgbe(4): Maintain one ifmedia per physical port instead of one per Virtual Interface (VI). All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults. The congestion channel map, which is still fixed, needs to be tracked separately now. Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering. Disable it by default when running on Intel CPUs. r328420: cxgbe(4): Do not display harmless warning in non-debug builds. r328423: cxgbe(4): Accept old names of a couple of tunables.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port. Before this change ifconfig diplayed potentially stale information for ports that were administratively down. - Always recalculate and reapply L1 config on a transceiver change. - Display PAUSE settings in ifconfig. The driver sysctls for this continue to work as well. r321103: cxgbe(4): New ioctls to flash bootrom and boot config to the card. r321179: cxgbe/t4_tom: Log more details about the newly ESTABLISHED tid to the trace buffer. r321390: cxgbe(4): Install the firmware bundled with the driver to the card if it doesn't seem to have one. This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters. These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision. These timers are already displayed in microseconds in the sysctl MIB. Add variables to track these tunables while here. r322123: cxgbe(4): Avoid a NULL dereference that would occur during module unload if there were problems earlier during attach. r322167: cxgbe(4): Add the T6 and T5 Unified Wire configuration files to the kernel, just like for T4, when the driver is compiled into the kernel. r322425: cxgbe(4): Save the last reported link parameters and compare them with the current state to determine whether to generate a link-state change notification. This fixes a bug introduced in r321063 that caused the driver to sometimes skip these notifications. r322549: cxgbe/t4_tom: Use correct name for the ISS-valid bit in options2. r322914: cxgbe(4): Dump the mailbox contents in the same format as CH_DUMP_MBOX. r322960: cxgbe(4): Verify that the driver accesses the firmware mailbox in a thread-safe manner. r322962: cxgbe(4): Remove write only variable from t4_port_init. r322964: cxgbe(4): vi_mac_funcs should include the base Ethernet function. It is already used in the driver as if it does. r322985: cxgbe(4): Maintain one ifmedia per physical port instead of one per Virtual Interface (VI). All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults. The congestion channel map, which is still fixed, needs to be tracked separately now. Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port. Before this change ifconfig diplayed potentially stale information for ports that were administratively down. - Always recalculate and reapply L1 config on a transceiver change. - Display PAUSE settings in ifconfig. The driver sysctls for this continue to work as well. r321103: cxgbe(4): New ioctls to flash bootrom and boot config to the card. r321179: cxgbe/t4_tom: Log more details about the newly ESTABLISHED tid to the trace buffer. r321390: cxgbe(4): Install the firmware bundled with the driver to the card if it doesn't seem to have one. This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters. These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision.

It is already used in the driver as if it does. r322985: cxgbe(4): Maintain one ifmedia per physical port instead of one per Virtual Interface (VI). All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults.

Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port.

This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters.

The ioctl can be used to collect the chip's internal state in a compressed dump file.

This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port. Before this change ifconfig diplayed potentially stale information for ports that were administratively down. - Always recalculate and reapply L1 config on a transceiver change. - Display PAUSE settings in ifconfig.

This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters. These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file.

It is already used in the driver as if it does. r322985: cxgbe(4): Maintain one ifmedia per physical port instead of one per Virtual Interface (VI). All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port.

The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections.

Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults. The congestion channel map, which is still fixed, needs to be tracked separately now. Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering. Disable it by default when running on Intel CPUs. r328420: cxgbe(4): Do not display harmless warning in non-debug builds. r328423: cxgbe(4): Accept old names of a couple of tunables.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port.

This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters.

The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision.

Add variables to track these tunables while here. r322123: cxgbe(4): Avoid a NULL dereference that would occur during module unload if there were problems earlier during attach. r322167: cxgbe(4): Add the T6 and T5 Unified Wire configuration files to the kernel, just like for T4, when the driver is compiled into the kernel. r322425: cxgbe(4): Save the last reported link parameters and compare them with the current state to determine whether to generate a link-state change notification.

Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults.

Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables.

In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering.

This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering.

These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision. These timers are already displayed in microseconds in the sysctl MIB. Add variables to track these tunables while here. r322123: cxgbe(4): Avoid a NULL dereference that would occur during module unload if there were problems earlier during attach. r322167: cxgbe(4): Add the T6 and T5 Unified Wire configuration files to the kernel, just like for T4, when the driver is compiled into the kernel. r322425: cxgbe(4): Save the last reported link parameters and compare them with the current state to determine whether to generate a link-state change notification. This fixes a bug introduced in r321063 that caused the driver to sometimes skip these notifications. r322549: cxgbe/t4_tom: Use correct name for the ISS-valid bit in options2. r322914: cxgbe(4): Dump the mailbox contents in the same format as CH_DUMP_MBOX. r322960: cxgbe(4): Verify that the driver accesses the firmware mailbox in a thread-safe manner. r322962: cxgbe(4): Remove write only variable from t4_port_init. r322964: cxgbe(4): vi_mac_funcs should include the base Ethernet function.

All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults. The congestion channel map, which is still fixed, needs to be tracked separately now. Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering. Disable it by default when running on Intel CPUs. r328420: cxgbe(4): Do not display harmless warning in non-debug builds. r328423: cxgbe(4): Accept old names of a couple of tunables.

The driver sysctls for this continue to work as well. r321103: cxgbe(4): New ioctls to flash bootrom and boot config to the card. r321179: cxgbe/t4_tom: Log more details about the newly ESTABLISHED tid to the trace buffer. r321390: cxgbe(4): Install the firmware bundled with the driver to the card if it doesn't seem to have one. This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters. These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision. These timers are already displayed in microseconds in the sysctl MIB. Add variables to track these tunables while here. r322123: cxgbe(4): Avoid a NULL dereference that would occur during module unload if there were problems earlier during attach. r322167: cxgbe(4): Add the T6 and T5 Unified Wire configuration files to the kernel, just like for T4, when the driver is compiled into the kernel. r322425: cxgbe(4): Save the last reported link parameters and compare them with the current state to determine whether to generate a link-state change notification. This fixes a bug introduced in r321063 that caused the driver to sometimes skip these notifications. r322549: cxgbe/t4_tom: Use correct name for the ISS-valid bit in options2. r322914: cxgbe(4): Dump the mailbox contents in the same format as CH_DUMP_MBOX. r322960: cxgbe(4): Verify that the driver accesses the firmware mailbox in a thread-safe manner. r322962: cxgbe(4): Remove write only variable from t4_port_init. r322964: cxgbe(4): vi_mac_funcs should include the base Ethernet function. It is already used in the driver as if it does. r322985: cxgbe(4): Maintain one ifmedia per physical port instead of one per Virtual Interface (VI). All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults. The congestion channel map, which is still fixed, needs to be tracked separately now. Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering. Disable it by default when running on Intel CPUs. r328420: cxgbe(4): Do not display harmless warning in non-debug builds. r328423: cxgbe(4): Accept old names of a couple of tunables.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port. Before this change ifconfig diplayed potentially stale information for ports that were administratively down. - Always recalculate and reapply L1 config on a transceiver change. - Display PAUSE settings in ifconfig. The driver sysctls for this continue to work as well. r321103: cxgbe(4): New ioctls to flash bootrom and boot config to the card. r321179: cxgbe/t4_tom: Log more details about the newly ESTABLISHED tid to the trace buffer. r321390: cxgbe(4): Install the firmware bundled with the driver to the card if it doesn't seem to have one. This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters. These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision. These timers are already displayed in microseconds in the sysctl MIB. Add variables to track these tunables while here. r322123: cxgbe(4): Avoid a NULL dereference that would occur during module unload if there were problems earlier during attach. r322167: cxgbe(4): Add the T6 and T5 Unified Wire configuration files to the kernel, just like for T4, when the driver is compiled into the kernel. r322425: cxgbe(4): Save the last reported link parameters and compare them with the current state to determine whether to generate a link-state change notification. This fixes a bug introduced in r321063 that caused the driver to sometimes skip these notifications. r322549: cxgbe/t4_tom: Use correct name for the ISS-valid bit in options2. r322914: cxgbe(4): Dump the mailbox contents in the same format as CH_DUMP_MBOX. r322960: cxgbe(4): Verify that the driver accesses the firmware mailbox in a thread-safe manner. r322962: cxgbe(4): Remove write only variable from t4_port_init. r322964: cxgbe(4): vi_mac_funcs should include the base Ethernet function. It is already used in the driver as if it does. r322985: cxgbe(4): Maintain one ifmedia per physical port instead of one per Virtual Interface (VI). All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults. The congestion channel map, which is still fixed, needs to be tracked separately now. Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port. Before this change ifconfig diplayed potentially stale information for ports that were administratively down. - Always recalculate and reapply L1 config on a transceiver change. - Display PAUSE settings in ifconfig. The driver sysctls for this continue to work as well. r321103: cxgbe(4): New ioctls to flash bootrom and boot config to the card. r321179: cxgbe/t4_tom: Log more details about the newly ESTABLISHED tid to the trace buffer. r321390: cxgbe(4): Install the firmware bundled with the driver to the card if it doesn't seem to have one. This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters. These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision.

It is already used in the driver as if it does. r322985: cxgbe(4): Maintain one ifmedia per physical port instead of one per Virtual Interface (VI). All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults.

Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port.

This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters.

The ioctl can be used to collect the chip's internal state in a compressed dump file.

This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port. Before this change ifconfig diplayed potentially stale information for ports that were administratively down. - Always recalculate and reapply L1 config on a transceiver change. - Display PAUSE settings in ifconfig.

This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters. These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file.

It is already used in the driver as if it does. r322985: cxgbe(4): Maintain one ifmedia per physical port instead of one per Virtual Interface (VI). All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port.

The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections.

Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults. The congestion channel map, which is still fixed, needs to be tracked separately now. Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering. Disable it by default when running on Intel CPUs. r328420: cxgbe(4): Do not display harmless warning in non-debug builds. r328423: cxgbe(4): Accept old names of a couple of tunables.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port.

This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters.

The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision.

Add variables to track these tunables while here. r322123: cxgbe(4): Avoid a NULL dereference that would occur during module unload if there were problems earlier during attach. r322167: cxgbe(4): Add the T6 and T5 Unified Wire configuration files to the kernel, just like for T4, when the driver is compiled into the kernel. r322425: cxgbe(4): Save the last reported link parameters and compare them with the current state to determine whether to generate a link-state change notification.

Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults.

Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables.

In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering.

This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering.

These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision. These timers are already displayed in microseconds in the sysctl MIB. Add variables to track these tunables while here. r322123: cxgbe(4): Avoid a NULL dereference that would occur during module unload if there were problems earlier during attach. r322167: cxgbe(4): Add the T6 and T5 Unified Wire configuration files to the kernel, just like for T4, when the driver is compiled into the kernel. r322425: cxgbe(4): Save the last reported link parameters and compare them with the current state to determine whether to generate a link-state change notification. This fixes a bug introduced in r321063 that caused the driver to sometimes skip these notifications. r322549: cxgbe/t4_tom: Use correct name for the ISS-valid bit in options2. r322914: cxgbe(4): Dump the mailbox contents in the same format as CH_DUMP_MBOX. r322960: cxgbe(4): Verify that the driver accesses the firmware mailbox in a thread-safe manner. r322962: cxgbe(4): Remove write only variable from t4_port_init. r322964: cxgbe(4): vi_mac_funcs should include the base Ethernet function.

The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults. The congestion channel map, which is still fixed, needs to be tracked separately now. Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables.

In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering. Disable it by default when running on Intel CPUs. r328420: cxgbe(4): Do not display harmless warning in non-debug builds. r328423: cxgbe(4): Accept old names of a couple of tunables.

The driver sysctls for this continue to work as well. r321103: cxgbe(4): New ioctls to flash bootrom and boot config to the card. r321179: cxgbe/t4_tom: Log more details about the newly ESTABLISHED tid to the trace buffer. r321390: cxgbe(4): Install the firmware bundled with the driver to the card if it doesn't seem to have one. This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters. These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision. These timers are already displayed in microseconds in the sysctl MIB. Add variables to track these tunables while here. r322123: cxgbe(4): Avoid a NULL dereference that would occur during module unload if there were problems earlier during attach. r322167: cxgbe(4): Add the T6 and T5 Unified Wire configuration files to the kernel, just like for T4, when the driver is compiled into the kernel. r322425: cxgbe(4): Save the last reported link parameters and compare them with the current state to determine whether to generate a link-state change notification. This fixes a bug introduced in r321063 that caused the driver to sometimes skip these notifications. r322549: cxgbe/t4_tom: Use correct name for the ISS-valid bit in options2. r322914: cxgbe(4): Dump the mailbox contents in the same format as CH_DUMP_MBOX. r322960: cxgbe(4): Verify that the driver accesses the firmware mailbox in a thread-safe manner. r322962: cxgbe(4): Remove write only variable from t4_port_init. r322964: cxgbe(4): vi_mac_funcs should include the base Ethernet function. It is already used in the driver as if it does. r322985: cxgbe(4): Maintain one ifmedia per physical port instead of one per Virtual Interface (VI). All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults. The congestion channel map, which is still fixed, needs to be tracked separately now. Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering. Disable it by default when running on Intel CPUs. r328420: cxgbe(4): Do not display harmless warning in non-debug builds. r328423: cxgbe(4): Accept old names of a couple of tunables.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port. Before this change ifconfig diplayed potentially stale information for ports that were administratively down. - Always recalculate and reapply L1 config on a transceiver change. - Display PAUSE settings in ifconfig. The driver sysctls for this continue to work as well. r321103: cxgbe(4): New ioctls to flash bootrom and boot config to the card. r321179: cxgbe/t4_tom: Log more details about the newly ESTABLISHED tid to the trace buffer. r321390: cxgbe(4): Install the firmware bundled with the driver to the card if it doesn't seem to have one. This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters. These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision. These timers are already displayed in microseconds in the sysctl MIB. Add variables to track these tunables while here. r322123: cxgbe(4): Avoid a NULL dereference that would occur during module unload if there were problems earlier during attach. r322167: cxgbe(4): Add the T6 and T5 Unified Wire configuration files to the kernel, just like for T4, when the driver is compiled into the kernel. r322425: cxgbe(4): Save the last reported link parameters and compare them with the current state to determine whether to generate a link-state change notification. This fixes a bug introduced in r321063 that caused the driver to sometimes skip these notifications. r322549: cxgbe/t4_tom: Use correct name for the ISS-valid bit in options2. r322914: cxgbe(4): Dump the mailbox contents in the same format as CH_DUMP_MBOX. r322960: cxgbe(4): Verify that the driver accesses the firmware mailbox in a thread-safe manner. r322962: cxgbe(4): Remove write only variable from t4_port_init. r322964: cxgbe(4): vi_mac_funcs should include the base Ethernet function. It is already used in the driver as if it does. r322985: cxgbe(4): Maintain one ifmedia per physical port instead of one per Virtual Interface (VI). All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults. The congestion channel map, which is still fixed, needs to be tracked separately now. Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port. Before this change ifconfig diplayed potentially stale information for ports that were administratively down. - Always recalculate and reapply L1 config on a transceiver change. - Display PAUSE settings in ifconfig. The driver sysctls for this continue to work as well. r321103: cxgbe(4): New ioctls to flash bootrom and boot config to the card. r321179: cxgbe/t4_tom: Log more details about the newly ESTABLISHED tid to the trace buffer. r321390: cxgbe(4): Install the firmware bundled with the driver to the card if it doesn't seem to have one. This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters. These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision.

It is already used in the driver as if it does. r322985: cxgbe(4): Maintain one ifmedia per physical port instead of one per Virtual Interface (VI). All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults.

Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port.

This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters.

The ioctl can be used to collect the chip's internal state in a compressed dump file.

This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port. Before this change ifconfig diplayed potentially stale information for ports that were administratively down. - Always recalculate and reapply L1 config on a transceiver change. - Display PAUSE settings in ifconfig.

This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters. These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file.

It is already used in the driver as if it does. r322985: cxgbe(4): Maintain one ifmedia per physical port instead of one per Virtual Interface (VI). All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port.

The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections.

Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults. The congestion channel map, which is still fixed, needs to be tracked separately now. Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering. Disable it by default when running on Intel CPUs. r328420: cxgbe(4): Do not display harmless warning in non-debug builds. r328423: cxgbe(4): Accept old names of a couple of tunables.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port.

This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters.

The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision.

Add variables to track these tunables while here. r322123: cxgbe(4): Avoid a NULL dereference that would occur during module unload if there were problems earlier during attach. r322167: cxgbe(4): Add the T6 and T5 Unified Wire configuration files to the kernel, just like for T4, when the driver is compiled into the kernel. r322425: cxgbe(4): Save the last reported link parameters and compare them with the current state to determine whether to generate a link-state change notification.

Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults.

Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables.

In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering.

This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering.

These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision. These timers are already displayed in microseconds in the sysctl MIB. Add variables to track these tunables while here. r322123: cxgbe(4): Avoid a NULL dereference that would occur during module unload if there were problems earlier during attach. r322167: cxgbe(4): Add the T6 and T5 Unified Wire configuration files to the kernel, just like for T4, when the driver is compiled into the kernel. r322425: cxgbe(4): Save the last reported link parameters and compare them with the current state to determine whether to generate a link-state change notification. This fixes a bug introduced in r321063 that caused the driver to sometimes skip these notifications. r322549: cxgbe/t4_tom: Use correct name for the ISS-valid bit in options2. r322914: cxgbe(4): Dump the mailbox contents in the same format as CH_DUMP_MBOX. r322960: cxgbe(4): Verify that the driver accesses the firmware mailbox in a thread-safe manner. r322962: cxgbe(4): Remove write only variable from t4_port_init. r322964: cxgbe(4): vi_mac_funcs should include the base Ethernet function.

All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults. The congestion channel map, which is still fixed, needs to be tracked separately now. Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering. Disable it by default when running on Intel CPUs. r328420: cxgbe(4): Do not display harmless warning in non-debug builds. r328423: cxgbe(4): Accept old names of a couple of tunables.

The driver sysctls for this continue to work as well. r321103: cxgbe(4): New ioctls to flash bootrom and boot config to the card. r321179: cxgbe/t4_tom: Log more details about the newly ESTABLISHED tid to the trace buffer. r321390: cxgbe(4): Install the firmware bundled with the driver to the card if it doesn't seem to have one. This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters. These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision. These timers are already displayed in microseconds in the sysctl MIB. Add variables to track these tunables while here. r322123: cxgbe(4): Avoid a NULL dereference that would occur during module unload if there were problems earlier during attach. r322167: cxgbe(4): Add the T6 and T5 Unified Wire configuration files to the kernel, just like for T4, when the driver is compiled into the kernel. r322425: cxgbe(4): Save the last reported link parameters and compare them with the current state to determine whether to generate a link-state change notification. This fixes a bug introduced in r321063 that caused the driver to sometimes skip these notifications. r322549: cxgbe/t4_tom: Use correct name for the ISS-valid bit in options2. r322914: cxgbe(4): Dump the mailbox contents in the same format as CH_DUMP_MBOX. r322960: cxgbe(4): Verify that the driver accesses the firmware mailbox in a thread-safe manner. r322962: cxgbe(4): Remove write only variable from t4_port_init. r322964: cxgbe(4): vi_mac_funcs should include the base Ethernet function. It is already used in the driver as if it does. r322985: cxgbe(4): Maintain one ifmedia per physical port instead of one per Virtual Interface (VI). All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults. The congestion channel map, which is still fixed, needs to be tracked separately now. Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering. Disable it by default when running on Intel CPUs. r328420: cxgbe(4): Do not display harmless warning in non-debug builds. r328423: cxgbe(4): Accept old names of a couple of tunables.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port. Before this change ifconfig diplayed potentially stale information for ports that were administratively down. - Always recalculate and reapply L1 config on a transceiver change. - Display PAUSE settings in ifconfig. The driver sysctls for this continue to work as well. r321103: cxgbe(4): New ioctls to flash bootrom and boot config to the card. r321179: cxgbe/t4_tom: Log more details about the newly ESTABLISHED tid to the trace buffer. r321390: cxgbe(4): Install the firmware bundled with the driver to the card if it doesn't seem to have one. This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters. These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision. These timers are already displayed in microseconds in the sysctl MIB. Add variables to track these tunables while here. r322123: cxgbe(4): Avoid a NULL dereference that would occur during module unload if there were problems earlier during attach. r322167: cxgbe(4): Add the T6 and T5 Unified Wire configuration files to the kernel, just like for T4, when the driver is compiled into the kernel. r322425: cxgbe(4): Save the last reported link parameters and compare them with the current state to determine whether to generate a link-state change notification. This fixes a bug introduced in r321063 that caused the driver to sometimes skip these notifications. r322549: cxgbe/t4_tom: Use correct name for the ISS-valid bit in options2. r322914: cxgbe(4): Dump the mailbox contents in the same format as CH_DUMP_MBOX. r322960: cxgbe(4): Verify that the driver accesses the firmware mailbox in a thread-safe manner. r322962: cxgbe(4): Remove write only variable from t4_port_init. r322964: cxgbe(4): vi_mac_funcs should include the base Ethernet function. It is already used in the driver as if it does. r322985: cxgbe(4): Maintain one ifmedia per physical port instead of one per Virtual Interface (VI). All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults. The congestion channel map, which is still fixed, needs to be tracked separately now. Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port. Before this change ifconfig diplayed potentially stale information for ports that were administratively down. - Always recalculate and reapply L1 config on a transceiver change. - Display PAUSE settings in ifconfig. The driver sysctls for this continue to work as well. r321103: cxgbe(4): New ioctls to flash bootrom and boot config to the card. r321179: cxgbe/t4_tom: Log more details about the newly ESTABLISHED tid to the trace buffer. r321390: cxgbe(4): Install the firmware bundled with the driver to the card if it doesn't seem to have one. This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters. These are supposed to be setup by the firmware so these tunables are for experimentation only. r321582: cxgbe(4): Some updates to the common code. - Updated register ranges. - Helper routines for access to TP registers. - Updated routine to read flash parameters. r321671: cxgbe/iw_cxgbe: Log the end point's history and flags to the trace buffer just before it's freed. r322014: cxgbe(4): Initial import of the "collect" component of Chelsio unified debug (cudbg) code, hooked up to the main driver via an ioctl. The ioctl can be used to collect the chip's internal state in a compressed dump file. These dumps can be decoded with the "view" component of cudbg. r322034: cxgbe(4): Always use the first and not the last virtual interface associated with a port in begin_synchronized_op. r322055: cxgbe(4): Allow the TOE timer tunables to be set with microsecond precision.

It is already used in the driver as if it does. r322985: cxgbe(4): Maintain one ifmedia per physical port instead of one per Virtual Interface (VI). All autonomous VIs that share a port share the same media. r322990: cxgbe(4): Do not access the mailbox without appropriate locks while creating hardware VIs. This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults.

Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists.

This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port.

This lets the driver recover automatically from incomplete firmware upgrades (panic, reboot, power loss, etc. in the middle of an upgrade). r321435: cxgbe(4): Display some more TOE parameters related to retransmission and keepalive in the sysctl MIB. Provide tunables to change some of these parameters.

The ioctl can be used to collect the chip's internal state in a compressed dump file.

This fixes a bad race on systems with hw.cxgbe.num_vis > 1. r323006: cxgbe(4): Update T6/T5/T4 firmwares to 1.16.59.0. r323026: cxgbe(4): Zero out the memory allocated for the debug dump. cudbg_collect seems to expect it this way. r323041: cxgbe(4): Add two new debug flags -- one to allow manual firmware install after full initialization, and another to disable the TCB cache (T6+). The latter works as a tunable only. Note that debug_flags are for debugging only and should not be set normally. r323069: cxgbe/t4_tom: Add a knob to select the congestion control algorigthm used by the TOE hardware for fully offloaded connections. The knob affects new connections only. r323078: cxgbe/t4_tom: There may not be a tid to update if the connection isn't established. r323343: cxgbe(4): Fix a couple of problems in the sge_wrq data path. - start_wrq_wr must not drain the wr_list if there are incomplete_wrs pending. This can happen when a t4_wrq_tx runs between two start_wrq_wr. - commit_wrq_wr must examine the cookie's pidx and ndesc with the queue's lock held. Otherwise there is a bad race when incomplete WRs are being completed and commit_wrq_wr for the WR that is ahead in the queue updates the next incomplete WR's cookie's pidx/ndesc but the commit_wrq_wr for the second one is using stale values that it read without the lock. r323514: cxgbetool(8): mode must be specified when creating the dump file. r323520: cxgbe(4): Ignore capabilities that depend on TOE when the firmware reports TOE is not available. r324296: cxgbe(4): Provide knobs to set the holdoff parameters of TOE rx queues separately from NIC rx queues instead of using the same parameters for both types of queues. r324379: cxgbetool(8): Do not create a large file devoid of useful content when the dumpstate ioctl fails. Make the file world-readable while here. r324386: cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0. r324443: cxgbetool(8): Do not close uninitialized fd on malloc failure. r324945: cxgbe(4): Read the MPS buffer group map from the firmware as it could be different from hardware defaults.

Change the congestion setting for TOE rx queues to match the drivers on other OSes while here. r325596: cxgbe(4): Do not request settings not supported by the port. r325680: cxgbe(4): Excluce mdi from the check against port capabilities. r325880: cxgbe(4): Combine all _10g and _1g tunables and drop the suffix from their names. The finer-grained knobs weren't practically useful. r325883: cxgbe(4): Sanitize t4_num_vis during MOD_LOAD like all other t4_* tunables. Add num_vis to the intrs_and_queues structure as it affects the number of interrupts requested and queues created. In future cfg_itype_and_nqueues might lower it incrementally instead of going straight to 1 when enough interrupts aren't available. r325884: cxgbe(4): Remove rsrv_noflowq from intrs_and_queues structure as it does not influence or get affected by the number of interrupts or queues. r325961: cxgbe(4): Add core Vdd to the sysctl MIB. r326026: cxgbe(4): Add a custom board to the device id list. r326042: cxgbe(4): Fix unsafe mailbox access in cudbg. r327062: cxgbe(4): Read the MFG diags version from the VPD and make it available in the sysctl MIB. r327093: cxgbe(4): Do not forward interrupts to queues with freelists. This leaves the firmware event queue (fwq) as the only queue that can take interrupts for others. This simplifies cfg_itype_and_nqueues and queue allocation in the driver at the cost of a little (never?) used configuration. It also allows service_iq to be split into two specialized variants in the future. r327332: cxgbe(4): Reduce duplication by consolidating minor variations of the same code into a single routine. r327528: cxgbe(4): Add a knob to enable/disable PCIe relaxed ordering. Disable it by default when running on Intel CPUs. r328420: cxgbe(4): Do not display harmless warning in non-debug builds. r328423: cxgbe(4): Accept old names of a couple of tunables.

This affects the transmit of the VF driver only. 305699: cxgbe(4): Update the pad_boundary calculation for T6, which has a different range of boundaries. 305702: cxgbe(4): Use smaller min/max bursts for fl descriptors with a T6. 305703: cxgbe(4): Deal with the slightly different SGE_STAT_CFG in T6. 305713: cxgbe(4): Add support for additional port types and link speeds. 305715: cxgbe(4): Catch up with the rename of tlscaps -> cryptocaps. TLS is one of the capabilities of the crypto engine in T6. 305827: cxgbe(4): Use the interface's viid to calculate the PF/VF/VFValid fields to use in tx work requests. 305852: cxgbe(4): Attach to cards with the Terminator 6 ASIC. T6 cards will come up as 't6nex' nexus devices with 'cc' ports hanging off them. The T6 firmware and configuration files will be added as soon as they are released. For now the driver will try to work with whatever firmware and configuration is on the card's flash. 305906: cxgbe/t4_tom: The SMAC entry for a VI is at a different location in the T6. 305908: cxgbe/t4_tom: Update the active/passive open code to support T6.

H A D | Makefile | diff 322134 Mon Aug 07 02:54:11 MDT 2017 sephe MFC 321762 hyperv: Add VF bringup scripts and devd rules. How network VF works with hn(4) on Hyper-V in non-transparent mode: - Each network VF has a cooresponding hn(4). - The network VF and the it's cooresponding hn(4) have the same hardware address. - Once the network VF is up, e.g. ifconfig VF up: o All of the transmission should go through the network VF. o Most of the reception goes through the network VF. o Small amount of reception may go through the cooresponding hn(4). This reception will happen, even if the the cooresponding hn(4) is down. The cooresponding hn(4) will change the reception interface to the network VF, so that network layer and application layer will be tricked into thinking that these packets were received by the network VF. o The cooresponding hn(4) pretends the physical link is down. - Once the network VF is down or detached: o All of the transmission should go through the cooresponding hn(4). o All of the reception goes through the cooresponding hn(4). o The cooresponding hn(4) fallbacks to the original physical link detection logic. All these features are mainly used to help live migration, during which the network VF will be detached, while the network communication to the VM must not be cut off.

How network VF works with hn(4) on Hyper-V in non-transparent mode: - Each network VF has a cooresponding hn(4). - The network VF and the it's cooresponding hn(4) have the same hardware address. - Once the network VF is up, e.g. ifconfig VF up: o All of the transmission should go through the network VF. o Most of the reception goes through the network VF. o Small amount of reception may go through the cooresponding hn(4). This reception will happen, even if the the cooresponding hn(4) is down. The cooresponding hn(4) will change the reception interface to the network VF, so that network layer and application layer will be tricked into thinking that these packets were received by the network VF. o The cooresponding hn(4) pretends the physical link is down. - Once the network VF is down or detached: o All of the transmission should go through the cooresponding hn(4). o All of the reception goes through the cooresponding hn(4). o The cooresponding hn(4) fallbacks to the original physical link detection logic.
